Hematological Parameters to Predict the Severity of Hyperemesis Gravidarum and Ketonuria / Parâmetros hematológicos para prever a gravidade da hiperêmese gravídica e da cetonúria

Abstract Objective Hyperemesis gravidarum (HG) is a pregnancy complication that can progress with persistent nausea and vomiting. The aim of the present study is to evaluate the relationship between hematological parameters and HG. Method A total of 532 pregnant women with HG who were admitted to the Department of Obstetrics and Gynecology between March 2019 and February 2021, and 534 healthy pregnant women with characteristics similar to those of the case group were included in the study. The hematological parameters of both groups were compared. In addition, the hematological parametersof patients with HG according to the severity of ketonuria were compared. Results Themean age of the HG group (n=532) was 26.3 ± 4.1 years, and that of the control group (n=534) was 25.9 ± 4.8 years. Among patients with HG, 46% (n=249) had ketone(+), 33% (n=174), ketone(++), and 21% (n=109), ketone(+++). The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were higher in the HG group than in the control group: 3.8 (2.8-5.8)/3.2 (2.6-4.0); p<0.001; and 135.2 ± 30.4/108.9 ± 62.2; p<0.001 respectively. The neutrophil count, NLR, and PLR were higher in the group with ketone(+++) than in the groups with ketone(+) or ketone(++): 7.6 ± 1.9/5.5 ± 2.4; p<0.001; 3.8(2.8-4.6)/2.9(2.3- 3.6); p<0.001; and 149.9 ± 48.0/135.9 ± 65.7; p<0.001 respectively. The mean corpuscular hemoglobin (MCH) level, the NLR, and the PLR were identified as independent predictors of the presence of HG and the level of ketone positivity in HG patients. Conclusion The NLR and PLR were high in patients with HG, suggesting the its inflammatory activity. They may be important markers associated with the presence and severity of HG.

Resumo Objetivo A hiperêmese gravídica (HG) é uma complicação da gravidez que pode evoluir com náuseas e vômitos persistentes. O objetivo deste estudo é avaliar a relação entre os parâmetros hematológicos e a HG. Método Foram incluídas neste estudo 532 gestantes com HG internadas no Departamento de Obstetrícia e Ginecologia entre março de 2019 e fevereiro de 2021, e 534 gestantes saudáveis com características semelhantes às do grupo de caso. Os parâmetros hematológicos foram comparados entre gestantes com e sem HG. Além disso, os parâmetros hematológicos foram comparados entre as pacientes com HG de acordo com a gravidade da cetonúria. Resultados A média de idade do grupo GH (n=532) foi de 26,3 ± 4,1 anos, e a do grupo de controle (n=534) foi de 25,9 ± 4,8 anos. Entre as pacientes com HG, 46% (n=249) tinham cetona(+), 33% (n=174), cetona(++), e 21% (n=109), cetona (+++). A razão de neutrófilos para linfócitos (RNL) e a razão de plaquetas para linfócitos (RPL) forammaiores no grupo HG do que no grupo de controle: 3,8 (2,8-5,8)/3,2 (2,6-4,0); p<0,001; e 135,2 ± 30,4/108,9 ± 62,2; p<0,001, respectivamente). A contagem de neutrófilos, a RNL e a RPL foram maiores no grupo com cetona(+++) do que nos grupos comcetona(+) e cetona(++): 7,6 ± 1,9/5,5 ± 2,4; p<0,001; 3,8 (2,8- 4,6)/2,9 (2,3-3,6); p<0,001; e 149,9 ± 48,0/135,9 ± 65,7; p<0,001, respectivamente. O nível médio de hemoglobina corpuscular (MHC), a RNL e a RPL foram identificados como preditores independentes da presença de HG e do nível de positividade de cetona em pacientes com HG. Conclusão A RNL e RPL estavam elevadas em pacientes com HG, o que sugere a sua atividade inflamatória. Elas podem ser marcadores importantes associados à presença e à gravidade da HG.

Alterações urinárias em cães com diabetes mellitus / Urinary alterations in dogs with diabetes mellitus / Alteraciones urinarias en perros con diabetes mellitus

A diabetes mellitus (DM) é uma doença comum na rotina veterinária, de caráter multifatorial, gerando graves consequências na saúde dos pacientes acometidos. O diagnóstico é possível por meio de manifestações clínicas apresentadas e da realização de exames laboratoriais complementares. Entre esses exames, estão a dosagem da glicose sérica e a urinálise, as quais trazem ao clínico diversas informações, que podem ser correlacionadas aos demais achados, tornando possível o diagnóstico conclusivo de DM. Dessa forma, o presente trabalho teve como objetivo avaliar as alterações urinárias e de glicemia em cães com DM. Para isto, foram analisados laudos de amostras urinárias e de glicose sérica de 15 animais, onde o diagnóstico foi conclusivo para DM. Verificou-se presença de glicosúria em 100% dos casos, sendo observado em 66,67% das amostras glicosúria maior que 1000 mg/dL e, em 33,33% amostras, de 500 mg/dL; a cetonúria esteve presente em 66,67 %; proteinúria em 66,67% e bacteriúria presente em 73,33 dos dados analisados. Já a hiperglicemia foi constatada em 13 pacientes (86,67%). Assim, conclui-se que a urinálise é um exame de suma importância para o estabelecimento do diagnóstico, da melhor terapêutica para cada caso e do prognóstico dos pacientes.(AU)

Diabetes mellitus (DM) is a common disease on the veterinary routine. It has a multifactorial character generating severe consequences on the health of the patient. It can be diagnosed by clinical manifestations and by making additional laboratory tests. These tests include the measurement of serum glucose and urinalysis, which provides the physician with additional information to be correlated with other findings, in order to reach a conclusive diagnosis of DM. Therefore, this study aimed at evaluating urinary and glycemic alterations in dogs with DM. It analyzed reports of urine and serum glucose samples from 15 animals with a conclusive diagnosis for DM. Glycosuria was present in 100% of the cases. In addition, it was also observed that in 66.67% of the samples, glycosuria was higher than 1000 mg/dL, and in 33.33%, it was 500 mg/dL. Ketonuria was present in 66.67% of the samples, while proteinuria was observed in 66.67%. Bacteriuria was present in 73.33% of the samples on the analyzed data. Hyperglycemia was observed in 13 of these patients (86.67%), and thus, it can be concluded that urinalysis is an extremely important test for diagnosis, to choose the best therapy for each case and prognosis of the patients.(AU)

Pancreatic ketoacidosis-a rare case report

Euglycemic Pancreatic Ketoacidosis is a syndrome of high anion gap acidosis in which the high anion gap is due to elevated serum ketone bodies comprising of acetone, aceto- acetate and beta hydroxyl-butyrate, due to increased peripheral adipose tissue breakdown by elevated serum lipase as a consequence of acute pancreatitis with normal blood glucose levels. There are multiple causes for ketonuria and/or ketonemia with or without acidosis like uncontrolled diabetes mellitus, usually of the insulin dependent type (diabetic ketoacidosis), lactic acidosis, prolonged starvation (starvation ketosis), ethanol ingestion (alcoholic ketoacidosis), sepsis, pregnancy and vomiting. Our patient was not a known diabetic and his blood glucose were always within normal limits, so this ketoacidosis cannot be attributed to Diabetes Mellitus. It cannot be attributed to starvation as our patient was not fasting when he got admitted and furthermore ketoacidosis is not a frequent manifestation of starvation adding to it that we transfused adequate amount of DNS and resumed oral intake during our observation period. It cannot be attributed to vomiting as our patient had only two episodes of vomiting. Our patient does not have any liver or kidney pathology and there is no history or evidence of alcohol intoxication. But, acute pancreatitis without diabetes-mellitus, causing ketoacidosis is a very rare presentation which is caused by high levels of pancreatic lipase in the circulation.

Different Response of Body Weight Change According to Ketonuria after Fasting in the Healthy Obese

The relationship between obesity and ketonuria is not well-established. We conducted a retrospective observational study to evaluate whether their body weight reduction response differed by the presence of ketonuria after fasting in the healthy obese. We used the data of 42 subjects, who had medical records of initial urinalysis at routine health check-up and follow-up urinalysis in the out-patient clinic, one week later. All subjects in the initial urinalysis showed no ketonuria. However, according to the follow-up urinalysis after three subsequent meals fasts, the patients were divided into a non-ketonuria group and ketonuria group. We compared the data of conventional low-calorie diet programs for 3 months for both groups. Significantly greater reduction of body weight (-8.6 +/- 3.6 kg vs -1.1 +/- 2.2 kg, P < 0.001), body mass index (-3.16 +/- 1.25 kg/m2 vs -0.43 +/- 0.86 kg/m2, P < 0.001) and waist circumference (-6.92 +/- 1.22 vs -2.32 +/- 1.01, P < 0.001) was observed in the ketonuria group compared to the non-ketonuria group. Fat mass and lean body mass were also more reduced in the ketonuria group. In addition, serum free fatty acid concentration after intervention in the ketonuria group showed significant more increment than in the non-ketonuria group. The presence of ketonuria after fasting may be a predicting factor of further body weight reduction.

Evaluation of the Clinical Significance of Ketonuria

BACKGROUND: Urine ketone test is commonly used to screen for diabetic ketoacidosis (DKA). Ketonuria also develops in patients with disease conditions other than DKA. However, the prevalence of DKA in patients with ketonuria is not known. We investigated the prevalence of ketonuria and characteristics of patients with ketonuria and estimated the prevalence of DKA among them to study the clinical significance of ketonuria as an indicator of DKA. METHODS: We studied 1,314 adult and 1,027 pediatric patients who underwent urinalysis. The prevalence of ketonuria in the different groups of patients, classified according to the types of their visits to the institution, was investigated, and the relationships between ketonuria and albuminuria, glycosuria, and bilirubinuria were evaluated. RESULTS: The overall prevalence of ketonuria was 9.1%. The prevalences of ketonuria in adult and pediatric patients were 4.3% and 15.2%, respectively. The prevalences of ketonuria were the highest in the adult (9.7%) and pediatric (28%) patients in the group that had visited the emergency department. Among patients with ketonuria, 7% adult and 3.8% pediatric patients showed glycosuria. CONCLUSIONS: This study showed that the prevalence of DKA in patients with ketonuria, defined as the simultaneous presence of ketone bodies and glucose in urine, was only 7%. Therefore, we concluded that ketonuria might be clinically significant as an indicator of acute or severe disease status rather than of DKA.
